Questions about nuba.io
How do I add nuba.io to app-ads.txt?
Add one line for each account nuba.io gives you: "nuba.io, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through nuba.io. The account ID must be the seller_id nuba.io lists for you in its sellers.json; nuba.io will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does nuba.io publish a sellers.json?
Yes. Its file at https://cdn.prod.website-files.com/689e5d8d3fa71e654230b5f4/691340c7049f73f9554b7c7b_1c33e0503f3f32bdb6f68e154b5c5642_sellers.json.txt listed 33 sellers when we last read it on 10 October 2026: 29 publishers, 3 intermediaries and 1 listed as both; 0% are confidential.
How many apps declare nuba.io in app-ads.txt?
410 apps in Stoqlab's data (delisted apps included) declare nuba.io: 409 with at least one DIRECT line and 1 with at least one RESELLER line, across 62 app-ads.txt files. Counts are recomputed daily.
Why do nuba.io lines fail verification?
Of 62 lines naming nuba.io, 7 contradict its sellers.json. The most common case is "Seller ID not found" (5 lines): Ask nuba.io for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
